Environmental Monitoring
Aggregator components use environmental monitoring hardware to detect transmit power readings, receive power readings, and
temperature updates.
To receive periodic power updates, you must enable the following command.
Enable environmental monitoring.

Dell#
Recognize an Over-Temperature Condition
An overtemperature condition occurs, for one of two reasons: the card genuinely is too hot or a sensor has malfunctioned.
Inspect cards adjacent to the one reporting the condition to discover the cause.
If directly adjacent cards are not normal temperature, suspect a genuine overheating condition.
If directly adjacent cards are normal temperature, suspect a faulty sensor.
When the system detects a genuine over-temperature condition, it powers off the card. To recognize this condition, look for the
following system messages:
CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (temperature reaches or
exceeds threshold of
[value]C)
CHMGR-2-TEMP_SHUTDOWN_WARN: WARNING! temperature is [value]C; approaching shutdown
threshold of [value]C
To view the programmed alarm thresholds levels, including the shutdown value, use the show alarms threshold command.
NOTE: When the ingress air temperature exceeds 61°C, the Status LED turns Amber and a major alarm is triggered.
Example of the show alarms threshold Command
